Contaminants found in Source Water

MDH is partnering with U.S. Geological Survey (USGS) on a project to test for unregulated contaminants in drinking water sources across the state. MDH is conducting this study to understand where unregulated contaminants occur and at what levels.  The results will guide future efforts in monitoring, source water protection, and development of health-based guidance values.
